I couldn't find a figure on the number of registered HN users, so I used the recent number of daily unique IPs from http://ycombinator.com/newsnews.html http://ycombinator.com/newsnews.html. That number is 22,000.
For a confidence level of 95% with a confidence interval of 4%, we'd need 584 votes.
I'd imagine there's a lot of science to polling which this calculation probably ignores.

Yep, everything about being sure we have an unbiased sample, which is not likely for a question like this. What does your calculation say about the grouping of the data into categories?
- durana 18y agoI don't think the calculation says anything about the grouping of data. Or does it? If you have an unbiased sample of 584 votes and 60% of the sample responded "25 - 30", could you say with 95% confidence that 60% (+/-4%) of the sampled population would select "25 - 30"?
